Green Roof Detention and Retention Research Interview with Dr. Anna Zakrisson

Want to learn more about vegetated roof detention and retention research? We met with Dr. Anna Zakrisson from the green roof laboratory of Green Roof Diagnostics in Culpeper, Virginia. Short version. Full interview: https://youtu.be/qot1KpJIjPc Green Roof Diagnostics: https://www.greenroofdiagnostics.com Dr. Anna Zakrisson, was interviewed for Purple-Roof by Folkert Tempelman from Studio Piso7. These are the latest advancements in green infrastructure stormwater management. Zakrisson is part of a team of green roof researchers investigating and improving green roofs. Their main focus so far has been stormwater management. Detention green roofs can reduce or replace grey infrastructure stormwater management solutions such as tanks and cisterns. _____ Green & Grey Stormwater Management Options https://www.purple-roof.com/post/what-stormwater-management-options-are-there How to Manage Stormwater with Green Infrastructure https://www.purple-roof.com/post/green-infrastructure-stormwater-management _____ Feel free to embed these videos on your website.

Urban flood resilience: Nanco Dolman

We met with water resilience expert Nanco Dolman in Amsterdam. Nanco Dolman is a leading professional in Water Resilient Cities at Royal HaskoningDHV and has long experience in both disaster water management, for example storm Sandy, as well as in preventative measures. Nanco shares with us a very interesting perspective and some visions of how our future cities could look like and function with regard to water management. The main message is to see water as a resource and work *with it* and not against it.

Nature-based solutions: Dr. Helen Toxopeus

We interviewed Dr. Helen Toxopeus, a researcher at Sustainable Finance Lab, Utrecht University on the importance of green roofs / vegetated roofs as nature-based solutions. Toxopeus is involved in the EU-wide project Naturvation, a project with the aim to assess what nature-based solutions can be achieved in cities, and what tools are required to realize urban sustainability goals. https://naturvation.eu/home Also, we wanted to understand more about the financial aspects of installing green roofs: what financial incentives are there available in the EU region? Folkert Tempelman from Studio Piso7 conducted the interview on behalf of Purple-Roof. Purple-Roof website: https://www.purple-roof.com/

Combined Sewer Overflows

What Is A Combined Sewer? written and narrated by Dr. Anna Zakrisson ____ Does your city smell of poo from time to time? It is quite likely that you have felt a whiff of such unpleasant odors after heavy rain events. But, have you ever stopped and asked yourself why this happens? You might not like the answer… The reason is: overflowing combined sewers. Find out how green roofs can help to mitigate this serious problem! ____ ______ Read the full article on the Purple-Roof blog: https://www.purple-roof.com/post/what-is-a-combined-sewer _______ Don't hesitate to contact us if you have any questions at info@purple-roof.com

What is green roof retention?

What is green roof retention? Written by Brad Garner and narrated by Dr. Anna Zakrisson. _____ Retention is the process of holding water on the green roof, i.e., preventing water from draining off the green roof. Retention has been the focus of the hydrologic design of green roofs over the past few decades. Many people familiar with green roofs but less familiar with other types of stormwater management might not realize that most engineers consider retention the “free gift with purchase” rather than their central stormwater goal. So, what is this odd thing, retention? The secret of green roof water retention is green Retention works like this: rain falls onto a relatively dry green roof, and the green roof absorbs the water, usually in pore spaces. Later, the sun comes out, and the plants use the rainwater to evapotranspire. This means that the water leaves the roof as vapor. Eventually, it rains again, and the process is repeated. A surprising amount is going on there. Let’s unpack it! ______ Read the full article on the Purple-Roof blog: https://www.purple-roof.com/post/green-roof-water-retention _______ Don't hesitate to contact us if you have any questions at info@purple-roof.com

Green Roof Plants - How do They Survive?! Part 2/2

Green Roof Plants - How do They Survive Written and narrated by Dr. Anna Zakrisson for Purple-Roof. www.purple-roof.com/ _____ Pests and green roof plants During which parts of your life did you get the most infections? If you’d allow me to make a qualified guess, I’d probably say that it has been during times of high stress, mentally and/or physically. If we sleep little, eat poorly, and stress a lot, we tend to get sick. In a way, this is also the case for plants, through their stress looks different. Plant stress can be things like too little (or too much) water, high UV radiation, too much shade, too little (or too much) nutrients, or nutrients in the wrong ratios. Usually, one moderate stressor won’t crash a system, but if several of them come together, well, then you end up with sick plants. Often, we apply pesticides and hope for the best. However, if the stressors aren’t being dealt with, we are just postponing the situation. As an example, we were once asked to remove grubs that were eating up the green roofs in Montgomery County MD. Instead of applying pesticides, we recommended that we needed to remove plant stress. You remove plant stress, and the plants themselves can deal with the grubs. Pesticides fix the system short-term but mess it up even more long-term. Pesticides are not only expensive but end up in downstream water bodies, which may destroy local ecosystems and risk violating local environmental regulations. Furthermore, the symbiotic relationships between the plants and microbes such as mycorrhizae might be killed by broad-spectrum pesticides. Destruction of this type of symbiosis means lower water and nutrient availability for the plants, which in turn means more stress. It is like applying a band-aid on a gaping wound. We are much better off taking a close look at what is stressing the plants in the first place: let’s focus on sustainability. _____ Read the article on the Purple-Roof blog! www.purple-roof.com/post/green-roof…do-they-survive ____ Don't hesitate to contact us if you have any questions or feedback! info@purple-roof.com

Green Roof Plants - How do They Survive - Part 1

Green Roof Plants - How do They Survive Written and narrated by Dr. Anna Zakrisson for Purple-Roof. www.purple-roof.com/ _____ Do green roof plants matter? Yes, absolutely! The vegetation on a green roof is a central part of the engine that drives evapotranspiration. Evapotranspiration helps to ensure efficient green roof stormwater management. Also, if the roof isn’t covered by a protective layer of vegetation, the soil might simply blow away or even flush away during a rainfall. Selecting green roof plants The choice of green roof plants is important and should be carefully considered. The layer of vegetation should be selected based on climatic region and be well-tailored to the soil. Vegetation and soil are closely linked, and healthy soil biology is essential for happy plants. If the vegetation layer crashes, the functionality of the roof is destroyed. ______ Read the article on the Purple-Roof blog! https://www.purple-roof.com/post/green-roof-plants-how-do-they-survive ____ Don't hesitate to contact us if you have any questions or feedback! info@purple-roof.com

Green Roof ROI - What's the Deal? by Purple-Roof

Green Roof ROI - What's the Deal? Written by Oscar Warmerdam and narrated by Dr. Anna Zakrisson https://www.purple-roof.com/ _____ Almost all green roofs are sold in regulatory environments where there are incentives, and rebates, but mostly requirements to build green roofs. Often, the million-dollar question is dodged: “What is the real economic benefit of building a green roof?” How is it possible that in Washington DC more or less every building has a green roof, but just over the border on the other side of the street in Fairfax County one rarely sees a green roof built voluntarily? We’d like to take a close look at this from a purely economic perspective without the environmental or architectural discussion. Just the pure finance. In the end, most green roof customers are not eccentric billionaires with millions to spend on do-good stuff. Sure, it’s fantastic if we can help the environment, but to be honest, most of us simply can’t save the world on our salaries. We must get something out of the investment. However, it is possible to do good and get a return on your investment when it comes to green roofs.
